In itself, I would go for Qual and sophistication like to give 5 stars, 3 stars I have to take her but because she is incredibly uncomfortable. I myself into it without grab something they managed to be placed so that it does not press on the back with either a corner or rests uncomfortably in the neck area. But I have never owned a Slingbag, maybe it is in the nature of these Tasschen.
Best try myself, I have sent them back and ordered a Rush 12.
